Encrypt your files and emails::
The first issue I'll address is personal computer security.
This is not too difficult to achieve with the wealth of freeware
and shareware programs available. I personally use PGP
(Pretty Good Privacy)
and this is available at www.pgpi.com.
Once PGP is set up you can use it to encrypt emails and text
files either stored locally or sent as attachments. Of course
the recipient has to be using PGP to be able to decode the files
or email as you use their public key to encrypt the files. Once
received the recipient then uses his (or her) secure key to decode
the message or file.
Beware of email attachments::
Another important issue is email. If you receive an email
from an unknown source then delete it straight away. I don't care
how much wealth, good times or whatever it promises you DELETE
THAT MAIL IMMEDIATELY. Snooper programs can be buried inside emails
and allow hackers TOTAL CONTROL over your PC. One of these snooper
programs was recently tested in my section and we managed to send
a mail to the boss telling him he was a w**ker but it came from
his secretary. She had no idea we'd done it but it was to prove
a point to the
boss. IT WORKED.
Being anonymous on
the net
Switch off Cookies::
Make sure "Accept Cookies" is switched off in your
internet browser settings. These cookies are little files with
details of your surfing habits and generally come from sites without
you knowing. If you have any on your machine they are usually
in a directory under windows called, strangely enough, "cookies".
Empty your Temparary Internet Files directory EVERY TIME you
log off the internet. This also shows any would be snoop where
you've been. Some browsers can be set to automatically empty this
when they close. Check your settings and see.
Switch off sharing::
Unless you share your files or printers on a home or small
company network there should be no reason to have "File and
Printer Sharing" setup on your PC. If it is then SWITCH IT
OFF. Hackers can exploit this to look into your machine and gain
control of it.
